Model: SL-TWSW-RPS
Bring raw flat panels to a more consistent thickness before coating or further finishing. Vertically running abrasive belts remove surface unevenness and excess material, while automatic thickness detection helps set the sanding position for each incoming workpiece. The fixed conveying height also makes the machine easier to integrate with continuous panel-processing lines.

Application Scenarios:
A wide belt sanding machine calibrates raw flat panels to a more consistent thickness while refining the surface before coating or further finishing. The sanding section uses vertically running abrasive belts, while the worktable remains fixed for easier connection with upstream and downstream equipment. Automatic thickness detection reads each incoming workpiece before sanding, helping the machine adjust the working clearance as panels move through the line.
Set the sanding process around the incoming material and the amount of stock that needs to be removed. Confirm:
Three standard widths cover different panel formats. SL-TWSW-RPS1300 handles 40–1300 mm working widths, SL-TWSW-RPS1000 covers 40–1000 mm, and SL-TWSW-RPS630 covers 40–630 mm. Power and machine weight vary with the selected size.
The sanding frames move vertically to set the machining clearance, so the conveyor path can stay at a fixed height. This arrangement helps you connect the sander with other equipment in a continuous production line without raising and lowering the whole worktable.
At the inlet, automatic thickness detection measures the incoming workpiece before it reaches the abrasive belts. The sanding frames then work at the required height while the panel continues through the machine.
Abrasive belts handle the main thickness sanding operation. A wide aluminum-alloy sanding pad follows the abrasive section to refine the surface and remove remaining burrs. Independent shaft hanging plates allow each sanding shaft to be adjusted separately, while the eccentric-shaft lifting mechanism can raise the front sanding frame during standby or an emergency stop.
Oscillating air nozzles clear sanding dust from the abrasive belt during operation. The heavy lifting cylinder supports the vertical movement of the sanding assembly, while the main motor remains close to the machine base.
You can place the machine within a wider surface treatment process before coating. Where sanding prepares boards for continuous finishing, it can also feed into a UV roller coating line after the required surface condition is reached.
The sanding system can be configured with different working widths, sanding-frame quantities, and lifting methods to suit the panel format and production layout. Final sanding settings should follow the actual substrate hardness, removal requirement, and surface condition needed for the next process.
Custom wide belt sanding machines of different sizes are available for various products, and the parameters will vary accordingly. Please contact us.
When the wide belt sanding machine is operating, the high-speed rotating grinding wheel drives the sanding belt to precisely sand the workpiece surface. The amount of sanding in one pass exceeds 0.5mm, ensuring that the surface of the raw material is flat, smooth, and uniform in thickness, thereby achieving optimal substrate flatness and coating adhesion for subsequent coating processing.
The core components of our wide belt sanders are all high-quality parts that have been proven in the market over a long period of time, such as Omron photoelectric sensors from South Korea, Kuroda solenoid valves from Japan, low-voltage electrical appliances from LS from South Korea and Chint from China, PLCs and frequency converters from Delta from Taiwan, and MCGS LCD screens, to ensure the long-term stable operation of the equipment.
Not limited to a single model, we offer customized designs to meet diverse needs. For example, when working independently, we recommend the configuration with a lifting worktable; when connected to a coating line, we recommend the configuration with a lifting sanding frame. Depending on the thickness and hardness of the materials, we offer a wider range of sanding units, including single-sander and triple-sander frames.
This wide-belt sanding machine features a fixed worktable design. Double-sanding frames move vertically to adjust machining clearance, facilitating production line connection and avoiding workpiece edge damage from the sanding belt.
Thanks to its advanced configuration, this wide-belt sander's feed inlet supports automatic, precise detection of each workpiece's thickness and transmits the data to the PLC control system to enable a fully automated sanding process.
The sanding axis features a sturdy 9mm seamless steel pipe paired with an eccentric shaft core and an NSK bearing. It's carefully crafted to maintain a balance error of just around ±0.02mm, preventing any missed or uneven sanding.
After carefully sanding the raw material, gently use this wide aluminium alloy pad to polish the surface once more. This helps to remove any remaining burrs and leaves the surface smooth and even, ensuring a consistent thickness throughout.
Each spindle is securely mounted on a separate sturdy hanging plate to ensure stable and reliable operation. Sanding deviation can be conveniently corrected by reversing the screw rotation, with each turn providing a precise 0.1mm adjustment.
The front sanding frame employs a cylinder-driven eccentric shaft mechanism for lifting while in standby mode. It can rapidly elevate the shaft during emergency shutdowns, thereby effectively preventing surface scratches and material damage.
A swing-type air-blowing device is mounted above the sanding belt to continuously clear dust during processing. It optimizes sanding quality and noticeably extends the service lifespan of the sanding belt, making the process more efficient.
A heavy air cylinder with a larger diameter, improved sealing, and increased durability ensures stable and accurate operation of the lifting heads. The main, heavy motor remains close to the ground to maintain stability and minimize vibration.
